... Typical topology is shown. www.murata-ps.com UNR Open-Frame Series DATEL’s 30-66W UNR Series deliver an excellent solution to situations in which users of modern DSP’s and CPLD’s requiring Amps of "low-voltage" (1.5-3.3V) current are constrained to drawing that power from a legacy 5V bus. These are non-isolated DC/DC converters that deliver Amps of 1.5-3.3V current from a 5V input ...

... On/Off Control pin should be referenced to Input/Output Return. I/O Filtering and Noise Reduction All models in the UNR 30-66W Series are tested and specified with an external 22μF output capacitor (200m ESR) and a 4000μF input capacitor with a 9.75Arms ripple-current rating. External input capacitance is required ...

... On/Off Control The On/Off Control pin may be used for remote on/off operation. UNR 30- 66W Series DC/DC converters are designed so that they are enabled when the control pin is pulled high or left open, and disabled when the control pin is pulled low (see Performance Specifi ...

... Note: Resistor values are Accuracy of adjustment is subject to tolerances of resistors and factory-adjusted, initial output accuracy. Temperature Derating The outstanding electrical efficiency of the UNR 30-66W Series' synchro- nous-rectifier design and the excellent thermal conductivity of its aluminum base PCB/Heatsink construction combine to eliminate the need for supple- mental forced-air cooling in the majority of routine applications ...
